Why? That IOS image should be fine; anything after SXH should permit 
IPv6 within VRFs, including BGP on the right feature set.

It should be fine; we use IPv6 within VRFs including BGP within the VRF.

The main caveat is that you can only run one BGP process, so it's all:

router bgp 65000
   address-family ipv6 vrf XXX
     neighbor 2001:db8::1 ...

Yes, it works on sup720.

Yes, it also works on sup2t.
